Background technique
Thereby the structure that scroll compressor adopts the radius variable that rotates that can make vortex suitably to keep moving vortex and determine the contact of vortex.The example of aforementioned mechanism is swing-bar mechanism.As the example of swing-bar mechanism, Japanese Unexamined Patent Publication No No.2008-208717 discloses a kind of scroll compressor, wherein, is formed with eccentric opening at the eccentric position place of lining.Driving pin is arranged in the position of the central axis on an end face that departs from main shaft, and driving pin is rotatably inserted in the eccentric opening of lining.Therefore, in the time of drive main spindle, the moving vortex rotatably mounted by lining rotates around driving pin, and can change thus the radius that rotates of moving vortex.
Summary of the invention
With regard to above-described traditional scroll compressor, even stop and when the driving of main shaft stops, lining still relies on inertial force to continue rotation when scroll compressor.Now, lining rotates around driving pin.Therefore, main shaft and lining collide and produce relatively large noise.
This explanation is provided for being reduced in the technology of the extraordinary noise producing when scroll compressor stops.
Thereby scroll compressor comprise housing, by the rotatably mounted cylindric running shaft of housing, be fixed to housing determine vortex, with determine vortex relative to forming the moving vortex of pressing chamber and being arranged in housing and being configured to allow moving vortex by the rotate driving mechanism of motion of rotating of running shaft.Driving mechanism comprises cam pin, and cam pin stretches out in running shaft from the end parts parallel of running shaft; And be combined with the lining of equilibrium block, this lining is arranged between cam pin and moving vortex and comprises eccentric opening, cam pin inserts in this eccentric opening, this lining is configured to rotate and also comprise equilibrium block in the mode of combination around cam pin, and this lining is configured to rotatably move with respect to running shaft.Between at least one in the lining and running shaft and the cam pin that are combined with equilibrium block, be furnished with resilient member, and resilient member restriction is combined with the scope that can be movable relatively that the lining of equilibrium block rotatably moves with respect to running shaft and around running shaft.
With regard to this scroll compressor, resilient member is arranged between at least one in lining and running shaft and the cam pin that is combined with equilibrium block.Therefore, when running shaft stopping and stopping and when the lining that being combined with equilibrium block continues to rotate in the sense of rotation at running shaft due to inertial force, resilient member restriction is combined with the rotation of the lining of equilibrium block with scroll compressor.Therefore, because resilient member absorbs collision impact or produces surface friction drag and make thus the rotational speed of the lining that is combined with equilibrium block decline, so, reduce the impact noise of the lining stopping period that is combined with equilibrium block.Therefore, can reduce the extraordinary noise that scroll compressor stopping period produces.Note, " rotatably motion " in this specification refers in the clockwise direction with counterclockwise and above moves.

The O type ring 100 that is attached to running shaft 39 is described referring now to Fig. 4.The surface 68 of the peripheral surface of running shaft 39 and equilibrium block 65 is at the upper overlapping certain length L3 of axial direction (x direction).Length L 3 is than length L 2 slightly short (amount in the gap between particularly, the short described other end 41 at running shaft 39 and surface 67).In the peripheral surface of running shaft 39, be formed with groove 43.Groove 43 is formed on the part place of length L 3 apart, one end with running shaft 39.In other words, groove 43 is formed on the position relative with the surface 68 of equilibrium block 65.Groove 43 is formed as the whole circle of peripheral surface one around running shaft 39, and O type ring 100 is fitted on groove 43.The diameter (, the cross-sectional diameter of O type ring (this definition is equally applicable to other O type rings herein)) of O type ring 100 is set for during the lining 60 that is combined with equilibrium block rotatablely moves with respect to running shaft 39 O type ring 100 can only hereinafter will be described at a C() near with the thickness of surperficial 68 adjacency.O type ring 100 is formed by resin or rubber, and the lubricant oil of resin or rubber and the refrigeration agent using in scroll compressor 10 or scroll compressor 10 is compatible.As the example of O type ring 100, can use HNBR(hydrogenated nitrile-butadiene rubber), NBR(nitrile butadiene rubber) or EPDM(ethylene propylene diene rubber), but O type ring 100 is not limited to these materials, and can use any material that meets above-mentioned compatibility.This is equally applicable to the resilient member using in following mode of execution and remodeling mode of execution.Notice, O type ring 100 is equivalent to the example of " annular, resilient, member ".
Be described in respectively the running shaft 39 in running shaft 39 and the state that is combined with lining 60 collisions of equilibrium block and do not collide with the lining 60 that is combined with equilibrium block and be combined with the position relationship of the lining 60 of equilibrium block, and also describe operation and the effect of present embodiment.
The lining that is combined with equilibrium block 60 forming as mentioned above rotates around cam pin 42.Particularly, in the time that running shaft 39 is driven and be rotated (clockwise direction rotation) in the direction shown in the arrow D of Fig. 2, the lining 60 that is combined with equilibrium block rotates around cam pin 42.Therefore, by the motion that rotates of the rotatably mounted moving vortex 24 of the lining 60 that is combined with equilibrium block.The motion that rotates based on moving vortex 24 acts on the equilibrium block 65 of the combined lining 60 that has equilibrium block of centrifugal force of moving vortex 24 and offsets.Based on equilibrium block 65, in reducing moving vortex 24 and determine the friction on vortex wall surface of vortex 26, suitably keep by moving vortex 24 and the sealability of determining the pressing chamber 22a that vortex 26 forms.
When the driving of running shaft 39 stops with scroll compressor 10 and while stopping, the lining that is combined with equilibrium block 60 just rotating around cam pin 42 is because inertial force rotates up (turning clockwise) in the side being represented by arrow D, and rotatably moves with respect to running shaft 39.Now, because the lining 60 that is combined with equilibrium block is engaged in eccentric rotary, so collide at the some C place of Fig. 2 with the peripheral surface of running shaft 39 on the surface 68 of equilibrium block 65, and limit its rotatable motion with respect to running shaft 39 (strictly speaking, equilibrium block 65 collides at the part place of the crossing point C on surface 68 along depth direction (x direction) with running shaft 39)., the surface 68 and running shaft 39 line adjacency of equilibrium block 65.Now, O type ring 100 is attached to the peripheral surface of running shaft 39.The diameter of O type ring 100 is set near the thickness that O type ring 100 can be only carry out adjacency the point C on surface 68 for.In other words, the diameter of O type ring 100 is set in the time being combined with the lining 60 of equilibrium block and colliding with running shaft 39 O type ring 100 and surface 68 for and carries out the thickness of adjacency.Therefore the lining 60 that, is combined with equilibrium block collides with the peripheral surface of running shaft 39 near the some C on surface 68 via O type ring 100.Therefore, impact when O type ring 100 has been alleviated the lining 60 that is combined with equilibrium block and collided with running shaft 39, and reduced impact noise.Therefore running shaft 39 and be combined with the extraordinary noise that the collision of the lining 60 of equilibrium block produces, can be reduced in scroll compressor 10 and stop time.
Fig. 3 illustrates the example of the state that the lining 60 that is combined with equilibrium block do not collide with running shaft 39 (being combined with the state that the lining 60 of equilibrium block is just rotatably moving with respect to running shaft 39).In the present embodiment, the diameter of O type ring 100 is set in the time being combined with the lining 60 of equilibrium block and colliding with running shaft 39 O type ring 100 and surface 68 for and carries out the thickness of adjacency.Therefore, as shown in Figure 3, in the time being combined with the lining 60 of equilibrium block and just rotatably moving with respect to running shaft 39, the O type ring 100 that is attached to running shaft 39 in the not state of adjacency of surface 68 of lining 60 that is combined with equilibrium block.According to previous configuration, during rotatablely moving with respect to running shaft 39 with the lining 60 being combined with equilibrium block, O type ring 100 is always compared with the configuration of surperficial 68 adjacency with running shaft 39, and the scope that can be movable relatively that is combined with the lining 60 of equilibrium block increases.Therefore the lining 60 that, is combined with equilibrium block can more suitably be adjusted that motion produces based on rotating of moving vortex 24, moving vortex 24 and act on the pressure of determining vortex 26.Particularly, even in the time that centrifugal force in scroll compressor 10 High Rotation Speed processes raises, rotatably move with respect to running shaft 39 owing to being combined with the lining 60 of equilibrium block, still can offset the centrifugal force of moving vortex 24 so be combined with the lining 60 of equilibrium block, and suppress the rising of the pressure on the vortex wall surface of vortex.
